From space, the human impact on the planet can be seen most clearly through the spread of cities. However, cities themselves are spreading into much larger sprawling areas around and between them. The planet has arguably entered the 'Peri-cene' – a new global human-environment system shaped by peri-urbanisation.
Around the world, peri-urban areas contain global hubs and local enclaves, sprawl and disorder, and crucial urban infrastructure. Peri-urbanisation leads to the the disruption of communities and livelihoods and, in particular, there is growing ecological disruption and climate risk.
Peri-urban areas, too often overlooked by policymakers and academics, are also crucial to the urban food-water-energy nexus and three United Nations UN Sustainable Development Goals (SDGs):
- (11) Sustainable Cities and Communities;
- (13) Climate Action; and
- (15) Life on Land.
Yet the peri-urban is difficult to identify and define which means that the interactions between peri-urbanisation and climate risk have been little studied; until now.
Between 2019 and 2021, the Peri-cene project is conducting a pilot assessment of global peri-urbanisation with its climate risk. Such work will help policymakers to work towards the realisation of the UN SDGs. Outputs include:
- a global typology and global assessment with an interactive Peri-urban Analysis Tool;
- new synergies and pathways to address the policy challenges in a ‘Policy Lab’ with 24 city-regions from around the world and includes UN Habitat, UN Global Compact on Cities, and ICLEI;
- in-depth case studies in Chennai, India and Manchester, UK; and,
- the co-creation of adaptive governance pathways to mobilise collective policy intelligence to address peri-urbanisation and climate risk at local, regional and international scales.
Overall, Peri-cene is an agenda-setting project, in theory and practice, that builds on major EU projects, global data resources, and on existing clusters of expertise in Chennai, Manchester and Stockholm.
